Rosaceae
Deciduous, Shrubs, Decorative fruit or berries

ROSA

The rose is the queen of flowers, the most loved and widely planted shrub in all temperate parts of the world. More than 14,000 varieties are grown. Although mostly deciduous, roses can be evergreen in mild climates. Their stems, sometimes quite prickly, may be erect, arching, trailing, or scrambling. Leaves are divided into three, five, or seven leaflets, usually with toothed margins.

Rosa x harisonii

Hybrid between R. foetida and R. spinosissima; very old rose that was taken westward by pioneers and still persists in California’s Gold Country and around old farmhouses. Grows to 6 ft. tall and 4 ft. wide, forming thickets of thorny stems and fine-textured foliage. Flowers (in late spring) are profuse, semidouble, bright yellow, and fragrant. Occasionally reblooms in fall in warmer climates. Showy hips. Vigorous, disease-free, hardy to cold, and (once established) resistant to aridity. Useful deciduous landscaping shrub.
